一、引言急回运动特性是曲柄滑块机构具有的重要特性。很多文献给出了曲柄滑块机构急回综合方法。但传统的方法对如下问题都未给出定量的办法,往往需要反复综合、验证才能得到满足要求的机构或证明无解: 1.给定行程速比系数K,综合满足许用传动角〔γ〕或同时使最小传动角γ_(min)为最大的曲柄滑块机构; 2.在满足许用传动角〔γ〕的条件下,综合行程速比系数K为最大的曲柄滑块机构。本文通过对曲柄滑块机构最小传动角方
First, the introduction of quick-return kinematic characteristics of the crank-slider body has the important characteristics. A lot of literature gives a comprehensive method of crank-slider mechanism rapid response. However, the traditional methods do not give a quantitative method to the following problems, often require repeated synthesis, verification to be able to meet the requirements of the agency or prove no solution: 1. Given a trip coefficient ratio K, to meet the allowable transmission angle 〔γ ] Or the minimum transmission angle γ_ (min) at the same time. 2. The crank-slider mechanism with the maximum total travel speed ratio coefficient K under the condition that the allowable transmission angle [gamma] is satisfied. In this paper, the minimum transmission angle of the crank slider mechanism side
